VAPOR-BURNER.

Specification of Letters Patent.

Patented June 11, 1912.

Application filed December 4, 1909. Serial No. 531,310.

To all whom it may concern;

Be it known that I, ARTHUR ISAAC BLANCHARD, a subject of the Kingdom ofGreat Britain, and residing at Islington, London, England, have inventedcertain new and useful Improvements in Vapor-Burners, of which thefollowing is a specification.

This invention relates to vapor burners and has for its object toprovide an arrangement therein whereby a fine delicatecleaner needle maybe conveniently guided into the jet orifice without injury to theneedle.

Another object is to provide a convenient and efficient means forholding and reciprocating the needle without obstructing the flow of gasto the orifice and without the possibility of leaking where theoperating means passes to the outside for manipulation. To this end Ihave provided a housing to which the cleaner needle is secured so as topermit lateral movement, the housing being movable in a guide which isspaced from the lamp frame so as to permit the passage of the gas to theorifice, a special gas-tight packing being provided where themanipulating means for the movable housing passes out from the burner.

In the accompanying drawing, Figure 1 shows a vertical central sectionof a lamp arranged according to this invention, Fig. 2 is a horizontalsectional view taken on the line 2, 2, of Fig. 1 looking downwardly, andFig. 3 is a detail vertical sectional view on an enlarged scale andtaken on the line 3, 3, of Fig. 1.

Like reference characters indicate like parts throughout the severalfigures of the drawing.

Referring more particularly to the drawings, reference character Adesignates the cleaner needle which is mounted at the free end of alightand flexible cleaner rod B arranged within a housing C and attachedthereto, as at C, by the end B in such a manner as to permit a limitedlateral movement to the cleaner needle A independently of the housing C.

The housing C is mounted in the guide D held in place by radiallyprojecting. fins D, the longitudinal axis of the guide being inalinement with the jet orifice E, so as to guide the cleaner needle Awhen the latter is in central position into the jet orifice, the cleanerneedle being constrained to pass into the jet orifice by the conicalwalls of the cup F surrounding the jet orifice (see Fig.

3) in the known manner. When the housing C is moved longitudinallytoward the jet orifice, the cleaner needle A can be easily guided intothe jet orifice, as the cleaner rod B is very flexible, even though theguide D be not in perfect alinement with the jet orifice. Thislongitudinal movement of the housing C is effected, for example, bymeans of a pinion G (see Fig. 1) engaging the rack H 011 the housing C(see Figs. 1 and 3) the pinion Gr being mounted on a spindle I passingoutside of the burner and provided with a milled head J or othersuitable means for rotating the same for communicating motion to thehousing C for operating the cleaner-pin.

An air-tight fitting is provided for the spindle I where it passesthrough the wall of the burner. This fitting, as illustrated, comprisesa long uniform bearing M ending in a round shoulder O which is formedgas-tight by grinding or otherwise, the spindle I being provided with acorrespondingly rounded shoulder P, the parts being held in position bymeans of a nickel spring R. In the example illustrated, the part I ofsaid spindle is of smaller diameter than the main part of the spindleand is attached to the shank S of the milled head J; and this shank S isprovided with a flange S between which and the shoulder O the spring Ris located.

The end B of the rod B is held in place by being screwed in to the end Oof the housing C It is particularly understood that the details ofconstruction of this device may be greatly varied without departing fromthe spirit and scope of the invention as defined in the appended claims.

I claim as my invention:

1. In a vapor burner, the combination of a nipple having a jet orificeand a conically walled cup surrounding the orifice, a guide in alinementwith the orifice, an elongated casing movable in the guide, a flexiblecleaner-rod partly within the secured at its inner end in the casing andextending the full length of the casing, and a fine delicate cleanerneedle mounted on the free end of the flexible cleaner-rod.

2. In a vapor burner, the combination of a nipple having a jet orificeand a conically walled cup surrounding the orifice, a guide in alinementwith the orifice, an elongated casing movable in the guide, a flexiblecasing and cleaner-rod partly within the casing and secured at its innerend to the casing and extending the full length of the casing, a

fine delicate cleaner-needle mounted on the free end of the flexiblecleaner-rod, and means for moving the elongated casing.

3. In a vapor burner the combination of a lamp frame, a nipple screwedinto the lamp frame and provided with a jet orifice and a conical cupsurrounding the orifice, a guide held fixedly in said nipple and havingradial fins on its exterior for holding the same in place, a housinglongitudinally movable in said guide, a cleaner needle in said housingand adapted to be guided into said jet orifice by said conical cup, andmeans for longitudinally moving said housing.

4. A vapor burner, comprising a vapor chamber having its wall providedwith a bearing bore having a uniform part and a round shoulderterminating said part, said Vapor chamber having an orifice, a cleanerneedle for the orifice, a movable part provided with a rack and carryingsaid needle,

a spindle passing through said bearing and Copies of this patent maybeobtained for five cents each, by addressing the Commissioner of Patents,Washington, D36.
